The Moxa NPort 6250 is a secure and versatile 2-port device server that bridges RS-232/422/485 serial devices to modern Ethernet networks. With integrated TLS 1.2 and SSHv2 support, it ensures encrypted transmission of critical data in industrial environments. For deployment flexibility, it supports both copper (RJ45) and optional fiber Ethernet (SC Multimode or Singlemode).
The device comes equipped with a 64 KB per-port buffer and an SD slot (up to 32 GB) to prevent data loss during temporary network outages. Its sturdy metal housing and wide operating temperature options make it ideal for demanding applications like automation, utilities, and transportation systems.
